AUTOMATIC GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 329.560, dated November 3, 1885.

Application filed December .39. 1884. Serial No. 151,445. (MorleL) lah-ntml in England May 30, 1884, No. 8,439.

To all whom it may concern:

Be it known that we, Hnc'roR A. HoLMEs and WATSON M. HOLlilnjb', of the village of Hoosick Falls, in the county of Rensselaer and State of New York, have made certain new and useful Improvements in Automatic Grain- Binders, which relate particularly to the-mechanism employed in tying the knot in matic binding present the binding material in the proper manner to the knot-tying device, which may be done by any of the well-known mechanical means.

In this specification, and drawings which make a part of the same, we have described as applied to our binder as heretofore made and as patented to us December 3, 1878, N 0. 210,533.

In order to enable make and accompanying drawings, making a part of this specification, in which Figure 1 represents in perspective the knottyer and the frame which supports it and by which it is attached to the machine. Fig. 2 is a View in perspective of the same, showing the reverse side of Fig. 1 with the driving mechanism omitted. ig. 3 is a view in perand to its upper end is fastened the collar or cap I). This collar 1) has a hub, I), projecting around which is coiled the spiral Around this and passing through the frame A,is the hollow shaft f, on end of which is fastened the upper and on its upper end imparted at the proper time all the motions to the knotter -jaws. The upper knotteraw, F, has a slight projection or ledge, f, on 1is upper periphery, extending from its polnt about two-thirds This slight prowhich always insures the stripper with the cord, and insures its positive action to strip the cord from the knotter-jaws. This projection then rises abruptly upwardly and outwardly, as shown at F, in order to present a carrying-arm to the cord to place the cord in proper position for making the knot, as will be more fully hereinafter described. This projection F gradually recedes to the level of the plane of the knot- A E, which we call the is fastened by two knotter-hooks being slid apart to show their screws to the frame A. (See Fig. 2.)

of metal, which supports the parts, as will be scribed.

the casting or frame A, and to is top of one of the l which extends This piece keeps it in serves as a rest for the cord and proper position during the first theknot. Upon the slde of the frame A, and at its lower end and opposite to the cord-rest, is fastened the detaching hook or stripper l), as shown in Fig. 1.

The frame A is constructed with a horn or extending rim or. flange b on ,cap.,b. This rim or downwardly-extending flange extends only partially around the outward periphery of the circular flange b, as shown in Fig. 4. The upper end of the coiled spring is clasped around the vertical edge of. the cap, and its lower end is clasped around a projection or pin projecting above the end of the thick tooth B on pinion B, as shown in Fig. 1. The object of this thick tooth B is to enable the operator to set the knot-tying device properly in mesh with the teeth on thequadrant or other device which drives it. No quadrant or other device for driving is shown in the drawings.

In Fig. 2 the cord a, which encircles the bundle, is shown with its two branches laid over the cord-rest just above the knot-tying jaws as they commence to tie the knot. The cord is shown broken off, one branch of which is held by the cord-holder, and the other is held by or passes through the eye of the needlearn1,and thence to the ball of cord on the machine. The rest E, over and upon which the cord rests, serves the purpose of holding the cord from falling or being drawn into the open space between the points of the knotterhooks and the central shaft. Motion is communicated by any well-known means to the pinion B,whichturns the hollow shaft f a pan. tial revolution, carrying the point of the upper knolter-jaw, F, toward the cord. The spiral spring 0, connected at its upper end to cap b, fast to shaft 9, and at its lower end to pinion B, fast to shaft f,draws the two knotterjaws together, and both knotterjaws are moved together until the projecting flange b strikes against the horn A of the frame A. During this movement of the knotter-jaws the upwardly and outwardly projectingarm of the flange F on the upper knotterjaw, F, strikes against these two branches of the eord, and the knotter-jaw F being beveled or chamfered off on its under side to meet a corresponding chamfer on thelower jaw, G, the two branches oi the cord are forced down below both knot: ter-jaws and under the point of the stripper D, (a depression being formed in the horizontal surface of the upper knotter-jaw, as

1 shown at f, to allow the twine-spacevto pass under the stripper,)and cross the two branches of the cord that are around the bundle. Thus both knotter-j aws at this time areenci rcled by When the flange. 5 b strikes against the horn A, asaforesaid, the

spring 0 is overcome, and the upper knotterjaw moves forward and forms aspace between the portions F and G ,of the two knotterjaws sufficient to receive between them the 3 two branches of the cord which at the commencement of the movement were lying across the cord-rest and on top of the jaws. When this is accomplished, the pinion Bis moved in areverse direction, andthenpper knotterjaw," F, moves toward the lowerknotterjaw, G, the projection F strikes against G on G, and closes the opening with the cord between them. At this time the cord-holder releases its hold on one branch of the cord and takes hold of and cuts oil the other branch, which extends to the ball. Both knotting-jaws continue to move together, the upper jaw moving the lower one with the cord encircling them, as before deseibed, until the two upper branches of .the cord strike against the detaching hook or stripper D, as shown in Fig. 1. These two branches of the cord will by the further movement be stripped off the jaws F and G and over the two branches of cord held in the opening between F and G, thus forming the knot. When the bundle is discharged, the branches held between F and G will be drawn out with the bundle. The knotter-jaws will continue to move in the same direction until they take the same position where they started, ready to form another knot.

The device hereinbefore described can be made to tie a knot without the twine-rest E; but it would require a larger amount of cord,

and involve the danger of fouling or breaking it.

Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is

1. The combination of the knotter-jaw F, having the ledge f, the depression f, and the abrupt projection F with the stripper D, substantially as described.

2. The combination of the upper jaw, F, having the ledge f and the abrupt projection F, and the lower knotter-jaw with stripper D, substantially as and for the purpose specified.

3. The combination of the upper jaw, F, having the ledge f and the abrupt projection F, and the lower knotter-jaw with the cord-rest E, substantially as and for the purposedescribed.

4.; In combination with the upper jaw, F,

having the ledge f and the abrupt projection F and the lower knotter-jaw, the stripper D, and cord-rest E, substantially as described.

5. In combination with the partially-rotating knotter-jaw F, having the ledge f and the abrupt projection F, the jaw G, the stripper D,and cord-rest E,located above theknotter-jaws and opposite, or nearly so, to each other, substantially as described.
